Melatonin daily dosage units

ABSTRACT

The present invention relates to a disposable container for a medicament or cosmetic agent for topical application, containing a single dose of melatonin or of a melatonin derivative which corresponds to a locally effective dose but which does not cause any systemic effect.

[0001] The present invention relates to a disposable container for a medicament or cosmetic agent for topical application, containing a single dose of melatonin or of a melatonin derivative which corresponds to a locally effective dose but which does not cause any systemic effect.

[0002] Melatonin-containing agents can be used for various medical and cosmetic purposes. For example, the document DE 101 10 418.9 discloses melatonin-containing compositions for topical application on the skin and in the hair.

[0003] The subject of the present invention is a disposable container for a medicament or cosmetic agent for topical application, containing a single dose of melatonin or of a melatonin derivative which corresponds to a locally effective dose but which does not cause any systemic effect.

[0004] The disposable container according to the invention permits application of a dose of melatonin or of a melatonin derivative which is locally effective but which causes no undesired change in the normal melatonin plasma level. The single dose of melatonin or of melatonin derivative which is applied according to the invention causes no significant elevation of the melatonin plasma level for example.

[0005] The expression “melatonin or melatonin derivative”, as it is used in the context of this application, includes melatonin and/or melatonin derivatives and salts, esters or complexes thereof. Preferred melatonin derivatives include, for example, 5-methoxytryptamine, 5-methoxytryptophan, 5-methoxytryptophol, 5-methoxyindole-3-acetic acid and 6-hydroxymelatonin.

[0006] The single dose according to the invention represents a dose which permits a positive cosmetic and/or therapeutic effect without significant changes in the plasma level. According to the invention, a single dose of from approximately 0.001 to approximately 1.0 mg of melatonin is preferred, and more preferably a single dose of from approximately 0.01 to approximately 0.2 mg of melatonin. Depending on the application area or the intended use of the agent, a single dose can be applied once or several times daily. In a preferred embodiment, the single dose corresponds to a daily dose, particularly preferably a daily dose to be used in the evenings.

[0007] The medicament or cosmetic agent is preferably present as a liquid formulation. Examples of suitable formulations for topical application of the agent are solutions, suspensions, emulsions, microemulsions, nanosystems, creams, gels, lotions, sprays, foams or ointments, and any other formulation which can be applied topically. The agent is particularly preferably provided in the form of a cosmetic solution.

[0008] Depending on its intended use, the medicament or cosmetic agent contained in the disposable container according to the invention can have different concentrations of melatonin or of a melatonin derivative. The agent preferably contains a concentration of approximately 0.001 to approximately 0.01% (by weight), more preferably approximately 0.003 to 0.004% (by weight) of melatonin or of a melatonin derivative. A particularly preferred concentration is approximately 0.0033% (by weight).

[0009] In one embodiment, the therapeutic or cosmetic agent contains melatonin or a melatonin derivative as sole active substance. The agent can, however, also contain one or more further active substances such as vitamin A, vitamin A acid or other vitamin A derivatives, biotin and/or gingko biloba.

[0010] In a preferred embodiment, the medicament or cosmetic agent contains a combination of the active substances melatonin or melatonin derivative with biotin and/or gingko biloba. The active substances in this embodiment can be present in different dosages. A particularly preferred dosage of this combination is from approximately 0.05 to approximately 0.2 mg, particularly preferably approximately 0.1 mg of melatonin or melatonin derivative, from approximately 0.2 to approximately 0.4 mg, particularly preferably approximately 0.3 mg of biotin, and from approximately 1.3 to approximately 1.7 mg, particularly preferably approximately 1.5 mg of gingko biloba. Gingko biloba can in this case be contained for example as an extract, in particular as a dry extract, and/or in the form of one or more ingredients.

[0011] In a further preferred embodiment, the agent contains a combination of the active substances melatonin or melatonin derivative and vitamin A, vitamin A acid or another derivative of vitamin A. In this preferred active substance combination, the dosage of melatonin or melatonin derivative is preferably from approximately 0.05 to 0.2 mg, particularly preferably approximately 0.1 mg of melatonin.

[0012] The medicament or cosmetic agent can also contain one or more cosmetic and/or pharmaceutical auxiliaries or additives, for example thickeners, minerals or perfumes.

[0013] Depending on the intended application or use, the disposable container according to the invention can contain different volumes of the medicament or cosmetic agent. In a preferred embodiment, the disposable container contains approximately 2.5 to approximately 3.5 ml, preferably approximately 2.9 to approximately 3.2 ml of the agent. A particularly preferred volume is approximately 3.0 ml.

[0014] The therapeutic or cosmetic agent can be filled into the container using any suitable method known in the prior art. The agent is preferably filled into the container under GMP conditions. In this way it is possible to ensure that the agent is sterile and that, when the agent is applied, no problems arise in respect of bacterial contamination.

[0015] The disposable container according to the invention can in principle be made of any desired material. Examples of preferred materials are plastics and mixtures of plastics. Examples of particularly suitable plastics are polyethylene, polyvinyl chloride, polystyrene or polypropylene, with particular preference being given to polyethylene.

[0016] Depending on its desired outward appearance, the disposable container can be transparent, non-transparent, colorless or colored. Any desired dyes can for example be added to the plastic in order to obtain a colored container. A non-transparent container is preferred for use if the agent contains light-sensitive substances, because a non-transparent container additionally affords protection from light.

[0017] The disposable container according to the invention can in principle have any desired shape. Examples of preferred containers are shown in FIGS. 1 and 2. A suitable disposable container preferably comprises a part in which the agent is contained, and a disposable closure piece which is connected to the lower part via a predetermined break line.

[0018] Simple and safe handling of the container is advantageously ensured by the fact that it preferably has, on its head, a disposable closure piece which is opened by turning it. The container can thus be easily opened. In addition, after opening, the agent can emerge only if pressure is applied. This pressure can for example be exerted by hand during the application. This property allows the user to correctly dose the agent and position it in a targeted manner. If the agent is to be applied to the scalp or hair, the opened container can be guided directly through the hair like a comb. This permits straightforward and safe handling of the container and correct dosing of the agent.

[0019] Depending on the intended use, the disposable container carries lettering either printed on or embossed and/or is provided with a label.

[0020] Two or more disposable containers can furthermore be connected to one another in a detachable manner. For example, 5 or 10 containers are preferably connected to one another and form an arrangement. A container or an arrangement of containers can also be packed, preferably in a lightproof package, particularly preferably in an aluminum bag for example.

[0021] The expression “aluminum bag”, as it is used here, includes bags made of aluminum and also bags which for example are coated with aluminum on the outside or inside. For example, bags made of one or more layers of plastic and/or paper can be coated with aluminum. A preferred bag comprises, for example, an aluminum-containing laminated foil which additionally includes polyethylene, polyester and/or paper.

[0022] A package, in particular a lightproof package, permits storage over a fairly long period of time without loss of efficacy of the agent. Furthermore, such a package can provide protection against gas loss.

[0023] Depending on the intended use, an aluminum bag in which one or more disposable containers are packed can be printed on and/or provided with a label.

[0024] In a further embodiment of the invention, a package unit comprising several arrangements of disposable containers is provided.

[0025] The invention is further explained by attached FIGS. 1 and 2.
